Oil Pressure Light/Gage The light and gage tell you if there could be a problem with the engine oil pressure. The oil light goes on when you turn the key to ON or START. It goes off once you start the engine. That's a check to be sure the light works. If it doesn't come on, be sure to have it fixed so it will be there to warn you if something goes wrong. When the light comes on and stays on, it means that oil isn't flowing through the engine properly. You could be low on oil and you might have some other system problem. United States Canada The gage shows the engine oil pressure in pounds per square inch (psi). Canadian vehicles show pressure in kilopascals (kPa). CAUTION: Don't keep driving if the oil pressure is low. If you do, your engine can become so hot that it catches fire. You or others could be burned. Check your oil as soon as possible and have your vehicle serviced. 2-75
